Abstract
Description
Die Erfindung betrifft einen Sack nach dem Oberbegriff des Anspruchs 1.The invention relates to a bag according to the preamble of claim 1.
Derartige Säcke sind bekannt. So zeigt zum Beispiel die
Das Dokument
Faltung an der Frontwand befestigt werden. Die Klappen reichen dann von der Rückwandung aus über die Faltung hinaus bis zur Frontwandung hinaus bis zur Frontwandung. Die Herstellung eines solchen Sacks ist aufwändig.Folding be attached to the front wall. The flaps then extend from the back wall beyond the fold to the front wall and out to the front wall. The production of such a bag is expensive.
Daher besteht die Aufgabe der vorliegenden Erfindung darin, einen Sack vorzuschlagen, bei dem der Bodenbereich eine größere Haltbarkeit aufweist. Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 erfüllt.Therefore, the object of the present invention is to propose a bag in which the bottom portion has a greater durability. The object is achieved by the characterizing features of claim 1.
Zu den zusätzlichen Vorteilen eines solchen Sackes gehört, dass sich durch das Vorhandensein des Bodendeckblattes eine Quaderoder Kastenform des gefüllten Sackes noch einfacher einstellt. Eine besondere Festigkeit weisen Säcke aus direktem Polyolefin-Material auf. In der Regel werden zu diesem Zweck Polyolefin-Fäden gebildet und zumeist monoachsial, das heißt entlang ihrer Längsachse, gereckt. Diese Fäden werden oft zu Flachbahnen verwebt, aus denen später Schläuche erzeugt werden. Die Fäden können allerdings auch direkt zu einem Rundschlauch verarbeitet werden. Dieses Polyolefin-Material und seine Eigenschaften sind bekannt. Sie sind unter anderem in der
Besonders vorteilhaft sind jedoch Schweißverfahren, bei denen beispielsweise das Polyolefin-Gewebe angeschweißt wird. Hierbei ist, wie erwähnt, zu beachten, dass die Festigkeit des Polyolefin-Gewebes durch die monoachsiale Ausrichtung der Makromoleküle in den Polyolefin-Bändchen nicht verloren geht.However, welding methods are particularly advantageous in which, for example, the polyolefin fabric is welded. It should be noted, as noted, that the strength of the polyolefin fabric is not lost due to the monoaxial orientation of the macromolecules in the polyolefin tapes.
Eine weitere vorteilhafte Möglichkeit in der Verarbeitung dieses Materials besteht darin, die Beschichtung, die oft über das Polyolefin-Bändchengewebe aufgebracht wird, anzuschweißen. Die Gewebe werden oft beschichtet, um insbesondere bei der Verfüllung staubfähigen Materials eine höhere Dichtigkeit des Gewebes herbeizuführen.Another advantageous possibility in the processing of this material is to weld the coating, which is often applied over the polyolefin ribbon fabric. The fabrics are often coated, in order to bring about a higher density of the fabric, in particular when filling dustable material.
Der erfindungsgemäße Sack weist eine Bodenfaltung auf, die um eine Achse vorgenommen wurde, die im Wesentlichen quer zur Längsachse des Schlauchstückes oder Schlauchstückbereichs verläuft. Eine solche Faltung oder Rollung lässt sich besonders leicht durchführen. Auch diese Faltung oder Rollung trägt zu der späteren Kastenform des befüllten Sackes bei und ist daher von besonderem Vorteil. Durch eine doppelte Faltung wird nicht nur die Stabilität des Bodenbereiches, sondern auch ihre Dichtigkeit erheblich und in überraschendem Masse gesteigert. Die Doppelfaltung führt einen noch stärkeren Boden herbei, der, insbesondere im Zusammenwirken mit dem Zettel, auch wieder die Kastenform des Sackes unterstützt. Bei der Anbringung des Zettels ist darauf zu achten, dass zumindest Teile der Bodenfaltung mit dem Zettel überdeckt werden, so dass die Faltung durch den Zettel geschützt wird. Je nach Zettel kann es jedoch auch ausreichend sein, wenn weite Bereiche ungeschützt verbleiben und wenn der Zettel beispielsweise in Form von Klebebändern lediglich Teilbereiche der Faltung überdeckt.The bag according to the invention has a bottom fold which has been made about an axis which runs essentially transversely to the longitudinal axis of the hose piece or piece of hose piece. Such a folding or rolling is particularly easy to perform. This folding or rolling contributes to the later box shape of the filled bag and is therefore of particular advantage. By a double folding not only the stability of the soil area, but also their tightness is significantly and surprisingly increased. The double folding leads to an even stronger bottom, which, in particular in cooperation with the slip, also supports the box shape of the bag again. When attaching the note, make sure that at least parts of the bottom fold are covered with the slip so that the fold is protected by the slip. However, depending on the slip of paper, it may also be sufficient if wide areas remain unprotected and if the slip covers, for example in the form of adhesive tapes, only partial areas of the fold.
Für die Herstellung der erfindungsgemäßen Säcke eignen sich Schlauchstücke, welche Gerad- und/oder Staffelschnitte aufweisen. Besonders einfach sind die erfindungsgemäßen Säcke jedoch im Geradschnitt herzustellen. Ein bevorzugter Einsatzbereich der erfindungsgemäßen Säcke dürfte in der Speicherung und dem Transport von Schüttgut, insbesondere von staubförmigen Gütern zu suchen sein. In diesem Bereich sind Säcke üblich, die ebenfalls eine Kastenform aufweisen, die jedoch mit gefalteten Klotzböden versehen sind. Diese Säcke sind aufwändiger herstellbar. Ebenfalls üblich sind Kreuzbodensäcke in diesem Bereich.For the production of the bags according to the invention are hose pieces, which have straight and / or Staffelschnitte. However, the bags according to the invention are particularly easy to produce in straight section. A preferred area of use of the sacks according to the invention is likely to be found in the storage and transport of bulk material, in particular dust-like goods. In this area bags are common, which also have a box shape, but which are provided with folded pad floors. These bags are more expensive to produce. Also common are cross soil sacks in this area.
Unter Fügeprozess ist in der vorliegenden Druckschrift alles zu verstehen, was Materialien miteinander verbindet. Ausdrücklich erwähnt wurden bereits Schweiß- und Klebeprozesse sowie Verbindungen von Kunststoffteilen mit Extrudat. Als Zettel lassen sich je nach den Anforderungen an die Stabilität des Sackes auch verschiedene Materialien einsetzen. Diese Materialien können gleich oder von dem Sackmaterial oder dem Schlauchstückmaterial verschieden sein. Bei besonders hohen mechanischen Belastungen kann Olefin-Gewebe verwendet werden. Hier sind ebenfalls wieder die Verbindungsmodalitäten beziehungsweise die bei der Verarbeitung von Polyolefin-Gewebe empfehlenswerten Verarbeitungsbedingungen einzuhalten. Erneut wird auf die Druckschrift
